FastAPI application for the dm_control Environment.
This module creates an HTTP server that exposes dm_control.suite environments
over HTTP and WebSocket endpoints, compatible with EnvClient.
Usage:
# Development (with auto-reload):
uvicorn server.app:app --reload --host 0.0.0.0 --port 8000
# Production:
uvicorn server.app:app --host 0.0.0.0 --port 8000
# Or run directly:
uv run --project . server
